Hm, i have a clean account and havent been HWID banned for Cold War yet. But, some time soon ill try out SC again. From previous experiences during MW:2019 whether it be warzone or multiplayer, if you didnt rage and/or be straight up blatant you could last for a long time.
But, it really depends on your playstyle, config setup, and how well you actually play the game itself.
I dont think ive ever gotten an account ban when using SC but i definitely have gotten a shadowban at some point due to playing blatant. I mean it wasnt hard to get the shadowban but tbh it didnt really matter because i could remove it whenever.
